. ing the fulcrum of the fork carrier backward relative to the base at different times as required to lower it and to throw off hay from the fork advantageously for building the lower portion of a staeki third, to provide means for simultaneously lowering the fork and moving the fork carrier rearward as required to adapt the machine for elevating hay and building a low or high stack: fourth, to provide means for lengthening and shortening the parallel jointed uprights of the fork carrier and locking the two parts of each jointed upright together in overlying position as required to make them rigid.

My invention consists in the construction,

arrangement and combination of parts as hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings in which Figure 1. is a top view of the base and the fork carrier lowered and in parallel position with the parallel sides of the base. Fig. 2 is a side elevation that shows the fork carrier in a perpendicular position and the fork at its highest point of elevation. Dotted lines indicate the uprights of the fork carrier shortened and fulcrumed further rearward on the base as required to lower the fork and to facilitate building the lower portion of a stack advantageously. Fig. 3 shows the means for detachably connecting a sweep with the base so it can be folded flat upon the base to facilitate transportation. shows a modified manner of rigidly connee-ting the overlying parts of the uprights of the fork carrier.

The numerals 1O designate the parallel sides of the base rigidly connected by cross pieces 12. To the outsides of the front end portions of the sides are pivoted short Fig. 4

length 13 of the uprights of the fork carrier and to the outsides of the parts 13 are pivoted the main and longer .parts 14 of the jointed uprights thus provided. l/Vhen the two parts 13 and 14 are in parallel and overlying position, as shown in Figs. 1 and 2, they are latched or locked together by means of catches 15 secured to the sides 10 of the base and latches 16 pivoted to the short lengths 13 of the uprights of the fork carrier. Or the two parts 13 or 1 1 may be rigidly con nected by removable bolts 17 as shown in Fig. 1, as required for moving them jointly to support the fork at the highest position possible as shown in Fig. 2.

The fork head consisting of two cross bars 18 and 19 is fixed to the upper end portions of the parts 14 and is reinforced by braces 20 fixed to the cross bars and the parts 14 of the uprights of the fork carrier as shown in Fig. 1. Fork teeth 21 are fixed to the cross bars 18and 19 to project vertically as shown in Fig. 2 and teeth 22 are combined with the teeth 21 to project forward horizontally and rigidly connected with each other by a cross bar 23. Supports 24 for the teeth 22 are pivoted to the cross bar 19.

A sweep consisting of two straight bars 25 fixed together at their top ends is detachably and pivotally connected with the sides 10 of the base by journals 26 fixed to their lower ends and extended into bearings in the sides 10 as shown in Fig. 3. A journaled brace 27 pivoted to the bars 25 allows the lower ends of the bars 25 to be moved as required for withdrawing the journals from their bearings and disconnecting the sweep from the base as required to facilitate shipping the machine by laying the sweep upon the base. A device 28 is attached to the members of the jointed brace 27 as shown in Fig. 3, and as required for making the brace rigid.

A hoisting tackle consisting of two direction pulleys 29 and 30 connected with the front cross piece 12 of the base and a pulley 31 connected with the top of the sweep and a rope 82 connected with the top of the sweep and passed over the three pulleys as applied as shown in Figs. 1 and 2 is provided for operating the sweep and fork carrier. A rope 35 is fixed to the fork and to the rear cross bar 12 of the base as required to restrict the motion of the fork and fork carrier as they are actuated for elevating and throwing off hay upon a stack.

Having thus set forth the purposes of my invention and the manner of its construction and use the practical operation and utility thereof will be obvious.

What I claim as new and desire to secure by Letters-Patent, is

1. In a hay stacker, a base having parallel sides, jointed uprights of a fork carrier pivotally connected with the sides of the base for carrying a fork to difierent points of elevation at different times.

2. In a hay stacker, a base having parallel sides, jointed uprights of a fork carrier pivotally connected with the sides of the baseand means for fastening the lower portions {3f the jointed uprights to the sides of the ase.

3. In a hay stacker, abase having parallel sides, a jointed fork carrier composed of two uprights and each upright consisting of 'a short lower part pivoted to the side of base and a long upper part pivotally connected with the upper end of the short lower part to operate as set forth.

4. In a hay stacker, a base having parallel sides, a ointed fork carrier composed of two uprights and each upright consisting of a short lower part and a long upper part pivotally connected and the lower end of the short lower part pivoted to the base and means to rigidly connect the short lower part with the long upper part in overlying position with each other and the sides of the base.

5. In a hay stacker, a base having parallel sides, a ointed fork carrier composed of two uprights and each upright consisting of a short lower part and a long upper part pivotally connected and the lower end of the short lower part pivoted to the base, a catch fixed to the long upper part and a latch pivoted to the short lower part to rigidly connect the short lower part with the long upper part in overlying position with each other.

6. In a hay stacker, a base, a jointed fork carrier composed of two uprights and each upright consisting of a short lower part and a long upper part pivotally connected and the lower end of the short lower part pivoted to the base and means to rigidly connect the short lower parts of the uprights with the base, to operate as set forth.

7. In a hay stacker, a base, a fork carrier composed of two uprights and each upright consisting of a short lower part and a long upper part pivotally connected at the lower end of the long upper part and the lower end of the short'lower part pivoted to the base, a catch fixed to the base and a latch pivoted to the short lower part to rigidly connect the short lower parts of the uprights with the base as set forth.
